```javascript
[
  { to: '/reports/dashboard', icon: 'pi pi-home', label: 'Dashboard' },
  { to: '/data-entry', icon: 'pi pi-receipt', label: 'Bonuri' },
  { to: '/reports/invoices', icon: 'pi pi-file', label: 'Facturi' },
  { to: '/reports/trial-balance', icon: 'pi pi-calculator', label: 'Balanță' },
  { to: '/reports/bank-cash', icon: 'pi pi-money-bill', label: 'Trezorerie' },
  { to: '/settings', icon: 'pi pi-cog', label: 'Setări' }
]
```

### Basic Usage

```vue
<template>
  <MobileTopBar
    title="Dashboard"
    :showMenu="true"
    @menu-click="showDrawer = true"
  />

  <MobileDrawerMenu
    v-model="showDrawer"
    :user="authStore.user"
    @logout="handleLogout"
  />
</template>

<script setup>
import { ref } from 'vue'
import MobileDrawerMenu from '@shared/components/mobile/MobileDrawerMenu.vue'
import { useAuthStore } from '@/stores/auth'

const showDrawer = ref(false)
const authStore = useAuthStore()

const handleLogout = async () => {
  await authStore.logout()
  router.push('/login')
}
</script>
```

### With Logout Callback

```vue
<MobileDrawerMenu
  v-model="showDrawer"
  :user="{ username: 'John Doe' }"
  :onLogout="async () => {
    await api.logout()
    router.push('/login')
  }"
/>
```

| `actions` | Array | `[]` | Array of action buttons to display |

### Action Object Structure

```typescript
interface ActionBarAction {
  label: string          // Button text (e.g., 'Salvează')

| 2 buttons | Side-by-side, equal width |
| 3+ buttons | Equal distribution |

### Basic Usage

```vue
<template>
  <MobileActionBar
    :visible="isMobile"

## Design Tokens for Mobile

### Layout Tokens

| Token | Value | Use |
|-------|-------|-----|
| `--header-height` | 56px | MobileTopBar & MobileBottomNav height |
| `--z-fixed` | 1030 | Fixed elements z-index |
| `--z-modal-backdrop` | 1040 | BottomSheet overlay |
| `--z-modal` | 1050 | BottomSheet content |

### Touch Target Sizes

```css
/* Minimum touch target: 48x48px */
.touch-target {
  min-width: 48px;
  min-height: 48px;
}

/* Button in top bar */
.top-bar-btn {
  width: 48px;
  height: 48px;
}
```

### Spacing for Mobile

| Token | Value | Mobile Use |
|-------|-------|------------|
| `var(--space-xs)` | 4px | Icon gaps, tight spacing |
| `var(--space-sm)` | 8px | Between nav items, card gaps |
| `var(--space-md)` | 16px | Card padding, content margins |
| `var(--space-lg)` | 24px | Section spacing |

### Mobile Content Padding

```css
/* Standard mobile content area */
.mobile-content {
  padding-top: 56px;    /* MobileTopBar */
  padding-bottom: 56px; /* MobileBottomNav */
  padding-left: var(--space-md);
  padding-right: var(--space-md);
}

/* When selection footer is visible */
.mobile-content-with-selection {
  padding-bottom: 80px; /* Higher for selection footer */
}
```

---

## Best Practices

### 1. Always Use Design Tokens

```css
/* ✅ CORRECT */
.mobile-card {
  padding: var(--space-md);
  border-radius: var(--radius-md);
  box-shadow: var(--shadow-sm);
}

/* ❌ WRONG */
.mobile-card {
  padding: 16px;
  border-radius: 8px;
  box-shadow: 0 1px 2px rgba(0,0,0,0.05);
}
```

### 2. Account for Fixed Headers/Footers

```vue
<template>
  <div class="view-container">
    <MobileTopBar title="My View" />

    <main class="view-content">
      <!-- Content that scrolls -->
    </main>

    <MobileBottomNav />
  </div>
</template>

<style scoped>
.view-content {
  padding-top: 56px;    /* TopBar height */
  padding-bottom: 56px; /* BottomNav height */
  min-height: 100vh;
  overflow-y: auto;
}
</style>
```

### 3. Test Both Light and Dark Mode

All mobile components support:
- Manual dark mode: `[data-theme="dark"]`
- System preference: `@media (prefers-color-scheme: dark)`

```javascript
// Toggle theme in DevTools:
document.documentElement.setAttribute('data-theme', 'dark')
```

### 4. Handle Safe Areas (Notch/Home Indicator)

```css
.mobile-bottom-nav {
  padding-bottom: env(safe-area-inset-bottom);
}

.mobile-content {
  padding-bottom: calc(56px + env(safe-area-inset-bottom));
}
```

### 5. Selection Mode Pattern

```vue
<script setup>
const selectedItems = ref([])
const isSelectionMode = computed(() => selectedItems.value.length > 0)

const toggleSelection = (item) => {
  const index = selectedItems.value.findIndex(i => i.id === item.id)
  if (index === -1) {
    selectedItems.value.push(item)
  } else {
    selectedItems.value.splice(index, 1)
  }
}

const clearSelection = () => {
  selectedItems.value = []
}
</script>
```

### 6. Combine Components for Complex Views

```vue
<template>
  <!-- Top Bar adapts to selection mode -->
  <MobileTopBar
    :title="isSelectionMode ? `${selectedCount} selectate` : 'Bonuri'"
    :showBack="isSelectionMode"
    :selectionActive="isSelectionMode"
    :actions="currentActions"
    @back-click="clearSelection"
    @action-click="handleAction"
  />

  <!-- Main Content -->
  <main class="content">
    <SwipeableCards :totalCards="kpis.length">
      <template v-for="(kpi, i) in kpis" #[`card-${i}`]>
        <KPICard :data="kpi" />
      </template>
    </SwipeableCards>

    <ItemList :items="items" @select="toggleSelection" />
  </main>

  <!-- Bottom Nav (hidden in selection mode) -->
  <MobileBottomNav v-if="!isSelectionMode" />

  <!-- Selection Footer (shown in selection mode) -->
  <MobileSelectionFooter
    :visible="isSelectionMode"
    :actions="selectionActions"
  />

  <!-- Filter Sheet -->
  <BottomSheet v-model="showFilters">
    <FilterForm @apply="applyFilters" />
  </BottomSheet>
</template>
```

## Troubleshooting

### Top/Bottom bars not fixed

**Problem**: Bars scroll with content.

**Solution**: Ensure `.mobile-top-bar` and `.mobile-bottom-nav` have `position: fixed`. Check for `overflow: hidden` on ancestors.

### Content hidden behind bars

**Problem**: Content is cut off at top/bottom.

**Solution**: Add padding to content area:
```css
.content {
  padding-top: 56px;
  padding-bottom: 56px;
}
```

### BottomSheet z-index issues

**Problem**: BottomSheet appears behind other elements.

**Solution**: BottomSheet uses `<Teleport to="body">` to avoid stacking context issues. Check for `z-index` wars in your CSS.

### Swipe conflicts with scrolling

**Problem**: SwipeableCards interferes with vertical scroll.

**Solution**: Component uses angle detection (30° threshold). Ensure cards have sufficient content area. Check `touch-action: pan-y` is set.

### Dark mode not working

**Problem**: Components don't respond to theme changes.

**Solution**: All components support both mechanisms:
1. Manual: `[data-theme="dark"]` on `<html>`
2. System: `@media (prefers-color-scheme: dark)`

Check that `data-theme` attribute is set correctly.

### Selection footer overlaps content

**Problem**: When selection footer appears, it covers list items.

**Solution**: Use dynamic padding:
```css
.content {
  padding-bottom: v-bind(isSelectionMode ? '96px' : '56px');
}
```
